ABSTRACT
A significant progress has been made in R&D on earthquake engineering and applications since the Korean government has launched modern earthquake hazard reduction programs in 1990’s after recognizing potential disastrous consequences of seismic events following the Northridge and Kobe earthquakes. In particular, there are currently active researches on the development of new seismic design concepts with the recognition that the design concept in low and moderate seismic regions cannot be the same as in high seismic region. This paper introduces research activities on Life-Cycle Cost and Limited Ductility Design concepts which have been developed suitable for the moderate seismicity in Korea.
